The BDA proposed two new formats, BDXL, the name given to new 100-Gbyte and 128-Gbyte discs; and IH-BD, a so-called "Intra-Hybrid" disc that will incorporate both read-only and rewritable layers. Specifications for both disc types will be published during the upcoming months. Both formats will be incompatible with existing hardware; however, new players designed to take advantage of the new formats will be able to play back existing Blu-ray discs (BDs) which are available in both 25- and 50-Gbyte capacity points.
